Service Overview

Failed bathroom waterproofing is a silent disaster that can lead to rotting floor joists, termite infestations, and collapsed ceilings. In Sydney, moisture-related building failures are all too common due to poor installation and building movement. We specialise in professional bathroom waterproofing for both new builds and remedial repairs across all metro areas. Our licensed experts use the highest-grade liquid membranes and bond-breaking technologies to ensure your wet areas stay 100% watertight. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, ensuring your bathroom meets all current AS 3740 standards. Don’t risk your home’s structure; let our family-owned team provide a technically credible finish today.

What You Get

Our bathroom waterproofing service is a multi-stage technical process designed for total property security. We don’t just paint the floor; we seal every critical penetration and junction in the room. The service includes surface preparation, the installation of bond-breakers at all wall-to-floor and wall-to-wall joints, and the application of high-performance liquid membranes. We pay special attention to the shower recess, the vanity area, and the bath surrounds. You receive a full waterproofing compliance certificate for your insurance and council records, along with our lifetime workmanship guarantee. We offer a $0 callout fee for assessments before 4pm today.

What We Handle

We manage bathroom waterproofing for all types of residential and strata properties right across the Sydney basin. Our scope covers master ensuites, main family bathrooms, and high-rise apartment wet areas. We are experienced in working with concrete slabs, compressed fibre cement (CFC) sheeting, and timber subfloors. Whether you are performing a luxury renovation in the Eastern Suburbs or building a new home in Western Sydney, our licensed team ensures every joint meets the strict Australian Standards. We provide technically credible fixes for both new installations and remedial membrane repairs, helping homeowners and builders achieve 100% compliance today.

How We Get It Done

We begin by preparing the floor and wall surfaces to ensure they are clean, dry, and free of dust. After providing an upfront fixed-price quote, we install the bond-breaker system, which allows the membrane to move independently of the building’s structure. We apply a high-bond primer followed by two coats of premium liquid membrane, ensuring total coverage of all waste outlets and tap penetrations. We take particular care to seal the shower water-stop angle to prevent water escaping into the main room. Once cured, we perform a final test to confirm the room is ready for tiling. We finish by Providing you with a compliance certificate. Save $65 by booking online today. Our family-owned team is here to help.

A waterproofing failure is the most expensive bathroom repair a homeowner can face; getting it done right the first time is the only smart choice. As a family-owned Sydney business for 25+ years, we focus on providing technically credible fixes that last. Our upfront pricing ensures transparency, and our lifetime workmanship guarantee gives you long-term security. We’ve helped over 10,000 homes stay dry, delivering reliability you can count on.

A failed waterproofing membrane is a serious building defect that can lead to rapid structural decay and concrete cancer. Whether it’s a small tear in a bathroom corner or widespread failure on a large balcony, you need a technically credible fix fast. We specialise in the professional repair of all types of waterproofing membranes across Sydney, using advanced liquid and sheet technologies to restore your building’s barrier.

Old, mouldy, or peeling silicone is more than just an eyesore; it is a critical weak point where water can seep behind your tiles and rot your home’s frame. Over time, standard silicone shrinks and pulls away from joints, especially in Sydney’s high-humidity wet areas and sun-drenched balconies. We provide professional silicone replacement services that ensure a 100% watertight and antimicrobial seal for your home. With over 25 years of experience, we use only high-grade sanitary and UV-resistant sealants that are designed to last. We provide an upfront quote before we start and a lifetime workmanship guarantee, giving you a technically credible fix that restores both the look and safety of your bathroom and balcony today.

Old, cracked, or porous grout is the leading cause of water ingress behind shower tiles, leading to timber rot and mould. Our professional shower regrouting service restores your shower’s waterproof barrier while giving your bathroom a fresh, clean appearance. We don’t just apply a ‘skin’ of grout over the old stuff; we manually remove the degraded material to ensure a deep and lasting bond. We understand Sydney’s building standards and use high-grade polymer-modified or epoxy grouts that are resistant to cracking and staining. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, making your shower look and function like new today.

A leaking shower can quietly destroy your home’s subflooring and structural timber without you ever seeing a puddle. By the time damp spots appear on the hallway carpet or the ceiling below, the damage is often extensive and expensive to fix. We specialise in non-invasive shower leak repairs that fix the issue without necessarily removing every tile. Our team understands how Sydney’s climate and common building methods can lead to membrane failure or grout degradation over time. We offer a 60-minute response to assess the leak and provide an upfront quote, using advanced silicone and sealing technologies to restore your bathroom’s integrity today.

A hidden water leak behind a wall or under a floor can cause thousands in structural damage before you ever see a puddle. If your water bill has spiked or you see damp spots on your ceiling, you need a precision diagnostic fast. We utilise advanced acoustic sensors and thermal imaging technology to find hidden leaks without having to break your walls apart. We understand Sydney’s high-pressure council mains that can stress internal pipework to the point of failure. With over 25 years of experience, we provide a 60-minute emergency response to find the leak and offer an upfront quote for the fix. Our family-owned team ensures your home is protected today.

An underground water main leak can waste thousands of litres of water every day, leading to high water bills and ground subsidence around your property. Because these leaks are buried deep under lawns, driveways, or gardens, they often go unnoticed for months. We provide specialised external leak detection services across Sydney, utilizing high-powered acoustic microphones and tracer gas to find hidden failures without digging up your yard. We understand how Sydney’s varied soil conditions — from coastal sand to western clay — can stress underground pipes. With over 25 years of experience, we provide a 60-minute emergency response to find the leak and offer an upfront quote for the fix today.
